No, it isn't. First, you have not actually established that Crist lied. Your mere assertion is not evidence; indeed, because you are so woefully misinformed about so many things, it's actually evidence to the contrary. Second, lying is not, in and of itself, a violation of his oath as the attorney general.
Let's take a hypothetical case. Joe Shlobotnik, Attorney General for the State of Confusion, comes into his office to start his work. He's physically tired, he just had to ground one of his teenage kids for not being home on time, and he just got a phone call telling him that a very close friend has died. In short, Joe's life is the pits at the moment.
His executive assistant greets him and asks, "How are you, boss?"
Joe says, "Fine."
He has just lied. Let us assume that the State of Confusion's laws are identical to Florida. Please explain exactly how Joe has violated his oath of office. I eagerly await your display of your legal expertise.
If you'd rather say CHARLIE CRIST LIED, that will work too. He forgot he was FL AG during the debate.
Again, please cite the specific lie he told, and please explain, in detail, how it violated his oath as Florida AG.
I am not going to repeat Charlie Crist's lie because that would be ridiculous. Anyway, it got Tom Gallagher more support.
